Common sense of multi strand copper core flexible cable

VV, the full name is PVC insulated PVC sheathed flexible cable, also known as soft sheath. The wire used in RVV is composed of multiple strands of thin copper wire, i.e. RV wire. RVV flexible cable can not only twist insulated cores with the same nominal cross-sectional area together, but also twist insulated cores with different nominal cross-sectional areas together. Linear computer laser typing, full meters and feet. The thermal insulation material adopts environmental protection PVC, which is environmentally safe. The conductor is made of 99.99% pure oxygen free copper. The copper wire has bright appearance, low resistivity, good conductivity and high safety. The quality of the copper core in the core wire affects the load borne by the wire. The eccentricity is low. It is produced with advanced equipment, with uniform thickness and high safety. Uneven thickness of insulation layer will cause sparks and affect power safety.

The products are suitable for household appliances, small electric tools, instruments and power lighting; RVV cable is the most commonly used cable in weak current system. Due to the variety of specifications, the number of core wires most directly reflected is uncertain. There are single or multiple cables. And the jacket. However, there are special requirements for the arrangement between the core wires. In normal use, the maximum temperature of conductor is 70 ℃, and flexible wires are used for indoor decorative lighting circuits. However, during its use, it should also be noted that the temperature in the long-term working environment should not exceed 70 ℃.
